LUBRICATIIQ'G ABEANGEYLEENT FOR INTERNAL-COMBUSTION ENGINES.

Application filed April 6,

To all Iv/20m it may concern Be it knowirthat l, lind n: lliorcnnnun, llTlZhT! m the Frenchlle ic, residing at aris. in the Republic oi i iancc, have invented new and usefulimprovements in iiuhricating Ara-any, ments for internal-Combustion Engines, of which the tollowing is a, specification. i I

a The lubrication otthe parts of an internal combustion engine is usually obtained by a circulation of oil carried out by pressure, or by mere splashing.

in the case of circulation under pressure, the oil is usually drawn from the bottom the lower crank-case by means of a pump, which by suitable connections distributes it to the (lil'i'erent parts of the e'sigrinc, whence it falls again into the lower crankcase; this do ice has the advantage of permitting the distribution of oil wherever it is necessary, but has an inconvenience in that it has a very variable working, with the wear of the mechanical parts which compose it.

The splashing: device does not present the some inconvenienceas the preceding method, :lfor it remains constant irrespectively ofthe wear. or the partso'f the engine, but on the ,-oi.it.rary it is not well adapted to the distribution of the oil.

The device which forms the object of the pro invention is intended to unite the advantages oi the two systems above men.- tioned. consists in principle in theruse it oi a paddle wheel disposed between two partitions of the crank case; the space between these two partitions forms a chamber which connected at its lower part with the bottom of the crank case forming; a basin contraining' a reserve supply of oil. By reason o the connection, the same level is attained in the basin and in the chamber of the paddle wheel; this latter by its rotation draws along! astreain of oil which rises and is colle in a chamber provided in the upper casino. Subsequently, by the simple action of gravity, the oil thus raised is distributed to the oil trol ls, having the scoops of the connecting ]'0( s dipping: therein, as well as the difl erent parts to belubricated.

in order to introduce at each instant into the troughs or containers a quantity of oil which is proportional to the power turnished by the engine, the oil isbrought to each of these through the intermediary of two concentric tubes, rotating one within the.

other, one of which acts in the same manner asthe body-oi" a cock, and the other. as the plug; the oil is brought byflthednnertube provided with an orifice oppositeeachcontainer to be supplied, while. the outer tube: is proi lded at this place with an aperture it suitable shape whereby its rotation about the first tube shall cause a variatlon in the section of passage. The actuating device effecting therotation of this outer tube is? connected with the actuating device used for opening): the throttle of the carburetting aparatus, andthus provides for the increase teed tothe containers in accordance with the power of the engine. l 1

longitudinal section of the The wheel C secured to the crankshaft rotates with this latter, and it rotates Within a chamber B which is separated from the rest or. the crank case of the motor, being only in communication at the lower part with the basin A; the oil contained in the basin thus enters the chamber B at the same level, this latter heinnj so adjusted that the paddles oi "thewheel C are caused to dip into the oil by a certain'amount, drawing this oil along" in their rotation, and thus form a liquid stream which then empties into the chamber D. The oil then passes into the tube E; the tube F being controlled at the same time as the throttle of the carburetting apparatus as it will be 'valve which is also actuated by any other well known means for the control of the carburettor by the accelerator. The rod K is articulated on the levers M and O by means ol-"tw'o ball and socket joints L and L respectively. V

In the containers H the scoops I of the connecting rods are caused to dip and the oil which is thus scattered will lubricate the diflierent parts of the engine, descending thence into the basin A whence it passes into the chamber B and is again elevated by the paddle wheel.

Having now described my invention, what I claim as new and desire to secure by Letters Patent 1s:

I. A lubricating arrangement for internal combustion enginescomprising in combina tion a crank case, an oil chamber in communication with said crank case at its bottom part a rotary shaft, a paddlewhee'l on said shaft adapted to dip intotheoil chamber,' an'upper storage chamber into which the oil may be raised by the paddle wheel, two concentrically arranged tubes provided with ports opposite the parts to belubricated, one of said tubes being in coinmunication with the said storage chamber and tion with the said stc' i iaoee means for-rotating one oi the tubes with. respect to the other. v

2. A lubricating arrangement for internal coi'ubustion engines comprising in combination a crank case, an oil chamber in communication with said crank case atits bottom part a rotary shaft a paddle wheel on said shaft adapted to dip into the oil chamber, an upper storage chamber into which the oil may be raised by the paddle wheel two cm uni-call" .gerl tn provided with ports opposite the parts to be lubricated one oi, said tubes being in communicae ch21 inbei, :urog ew ating member for rotating one of the tubes with respect to the otherand means for connecting said operating member to the controlling ll'lGHlbGl for the throttle valve of the carburetter whereby the flow of oil will vary according to the speedot the engine v 3. A lubricating arrangement for internal combustion engines comprising in combination a crank case, an oil chan'iber in comnuniicatien with said eranlr case at its bottom part, a rotary shaft, apaddle wheel on said sh att adapted to dip into the oil chamber, an upper storage chamber into which the oil may be raised by the paddle wheel, two concentrically arranged tubes provided with ports one of said tubes being in communication with the said. storage chamber, means rot rotating one of the tubes with respect to the other and oil containers in vertical alignment with said ports and be low the sanie'and into which the scoops or the connecting rods are adapted to dip.

l'n testimony whereof I have signed my name to this specification.
